Web crawling is the automated process of discovering and downloading pages by recursively following hyperlinks. A crawler:
Starts with seed URLs.
Fetches each page (via Proxied 4G/5G IPs) to avoid blocks.
Extracts links and repeats until a stopping rule (depth, robots.txt, or queue exhaustion).
Rotating carrier-grade IPs on every request prevents rate-limit bans and geographic bias. For ethical considerations, obey robots.txt and crawl-delay directives.
